Don't call widget()->update() in our resizeEvent()! Resizing windows with

Plastik decorations feels faster now.

There already is something which triggers PaintEvents, I don't understand why
this is. However paintEvent() has actually been called 2 (!) times for every
resize event.
It seems that other window decorations have the same problem, I will check that
later.
